The owner of this ’08 STi had his original motor let go on him while at the track. As a racing enthusiast, rather than going back to the dealership and trying to get the motor covered under warranty he decided to step up his game and take this car to the next level.

The stock block was tossed in favor of a Raw Performance Street Series Block. The Street Series Block includes forged CP Pistons with high performance rings, STi forged rods, and a STi forged crankshaft. The forged pistons in this block offer greater strength than the original cast pistons the STi comes equipped with. The new motor was assembled using stock heads for now, although our customer is probably going to have some head work done in the future.

The owner of the vehicle chose to run the P&L rotated mount turbo kit. At the heart of this kit is a GT35r with an .82 a/r hot side housing. Due to the larger turbo, the stock top mount was replaced with a larger TurboXS unit. Some of the additional supporting mods include upgrading to a TiAL 44mm wastegate, HKS SSQV blow off valve, Deatsch Werks 850cc injectors, a Walbro 255lph fuel pump, Perrin equal length manifold, a custom oil catch can, and a South Bend FE Series clutch.

The car put down 388whp on our dyno running 93 octane. (Dyno Chart coming soon!)
